General Mach Discussion / Re: Lost Steps
« on: July 06, 2011, 12:57:19 AM »
I understand your frustration S but your machine should follow the instructions it is given by Mach and be in exactly the position the Mach DRO says it is. When there is a discrepancy, as in your case, then for some reason steps have been lost (or gained). Gained steps are often caused by electrical noise pickup but steps gained in one direction can appear as steps lost when the axis travels in the opposite direction. Lost steps are often caused by insufficient drive torque or mechanical problems.
As your machine is belt driven, could the belt be slipping or jumping a tooth on the pulley ?.
Have you checked the tightness of all the grub screws associated with the drive train to the Z Axis ?.
